1Choose the destination channel
Open the Slack channel where you want the mail to appear. You need permission to add integrations; on some plans the Email app is admin-gated.
Send email straight into a Slack channel
Turn on the Email app for a channel and Slack hands you an address — forward anything to it and it posts in five minutes.
The process
The full click-path to a working channel email address. Crumbs map to Directions steps.
Directions
2Open the channel name menu
Click the channel name at the top to open its settings, then go to the Integrations tab.
3Send emails to this channel
Under Integrations choose Send emails to this channel (this installs the Email app if it isn't already). Give it a name and an optional icon.
4Copy the generated address
Slack generates a unique, long inbound address for that channel. Copy it.
channel-name-aB3xY9z@yourworkspace.slack.com
5Point a sender at it
Forward a test email to the address, or set it as the notification recipient in a vendor tool. Each message posts to the channel with the subject as the title and the body expandable inline.
Common issues & fixes
There's no "Send emails to this channel" option.
The Email app is disabled for your workspace or your plan, or you lack permission. A workspace admin can enable it under app management.
Forwarded mail never appears.
Auto-forwarding from Gmail/Outlook often needs a confirmation step. Check the forwarding rule was verified, and send a direct test first.
Posts are huge walls of text.
HTML-heavy emails expand fully. Send plain-text alerts where possible, or use the collapse toggle Slack adds to long messages.
You need to retire the address.
Open the Email app's settings from the channel integrations and remove it — the address stops accepting mail immediately.
